David Henche, Director of Marketing and Communication at LeasePlan Spain, pointed out that "in order to draw conclusions, the study does not take as a reference the consumption data (kw/h) of the vehicles used for the tests but focuses on the obtained ranges". Henche explains that "consumption is a variable factor according to the users’ driving habits, and yet the autonomy offered by the on-board computer of each vehicle is better adjusted to the real tested autonomy”.
It has been identified that the recharging times in conventional plugs used during the tests have been very high. Therefore, if the use of the electric vehicle is going to be daily, practically exhausting the battery, it will be essential to have an installation and a fast charger that reduces waiting times and guarantees maximum mobility for the driver.
Although it is not the main indicator of the study, it should be noted that the differences in consumption between using, or not using, an efficient mode in an EV can be between 5 and 10%. In electric cars that allow different levels of energy recovery to be selected, the difference is greater.
"In the journey where more energy is regenerated is in the interurban roads, as it is where more speed variations occur for longer. Using efficient modes on motorways hardly affects the autonomy, if traffic is fluid there is hardly any regeneration of energy", explains Henche.
In EVs that have several efficient driving modes, using the most extreme of them has multiple limitations, since it turns off the air conditioning and reduces the maximum available speed.
Also, the differences in consumption between having activated, or not, the air conditioning varies between 5 and 20%. This depends on the average speed and the interior temperature of the car - the higher the temperature, the shorter the range. In cities, unlike highways, it is where the use of air conditioning has the greatest impact on the final consumption of the electric vehicle. The effect of the air-conditioning consumption on the final consumption of the car is less the faster it is driven.
